Create an IAM role - Amazon EKS
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Create an IAM role

Each cluster where you install Amazon Distro for OpenTelemetry (ADOT) must have this role to grant your Amazon service account permissions. Do these steps to create and associate your IAM role to your Amazon EKS service account. For more information, see IAM roles for service accounts.

  1. Creating an IAM OIDC provider for your cluster.

  2. Create your service account and IAM role. Note the following flags included in this command:

    • For the --name flag, specify the name of the service account you want to create. In this example, it is adot-collector.

    • For the --namespace flag, specify the namespace your service account will reside in; for this example you will use the default namespace.

    • For the --cluster flag, specify the name of your cluster.

    • Use the --attach-policy-arn parameter to specify the managed IAM policy for the integration you are using to the role. For example, if you are using ADOT Collector to send metric data to CloudWatch, you specify the CloudWatchAgentServerPolicy managed policy.

    • The --override-existing-serviceaccounts flag is for a service account already created in the cluster without an IAM role. You can exclude this if the service account does not have an IAM role.

      Enter the following command considering the previous notes:

eksctl create iamserviceaccount \
    --name adot-collector \
    --namespace default \
    --cluster my-cluster \
    --attach-policy-arn arn:aws-cn:iam::aws:policy/AmazonPrometheusRemoteWriteAccess \
    --attach-policy-arn arn:aws-cn:iam::aws:policy/AWSXrayWriteOnlyAccess \
    --attach-policy-arn arn:aws-cn:iam::aws:policy/CloudWatchAgentServerPolicy \
    --approve \
    --override-existing-serviceaccounts

In the following collector configurations, the serviceAccount: adot-collector field to the configuration has been added to use IAM roles for service accounts.
